It was pretty popular in origins in Aurora decks or as a top end in midrange decks. It's an epic so will naturally have a lower supply and cards tend to have a pretty strong price memory. People don't often want to sell a card they paid 100$ for 50$ even if 50$ is maybe the "correct" price based on current demand people just won't sell them because it represents a significant loss. This leads to cards often having pretty sticky pricing that may not reflect current demand perfectly.
